PECIFICATION forming part of Letters Patent No. 652,446, dated June 26,1900.

Application filed April 20, 1900.

' that the electric current can be concentrated or distributed in anyplace of the bath.

In the annexed drawings, Figure 1 is a front View of the bath-tub. Fig.2 is a cross-sec tion of the same. Fig. 3 shows the mannerin which theelectrodes are fastened.

The bath-tub, Fig. 1, is of a trapezoidal shape and consists of wood orother isolating substance. The front wall a of the bath-tub is providedwith a metal band I), to which one pole of the battery is fixed. Anumber of metal rods are fixed to the rim of the bathtub above thismetal band I) in such a way that each can be turned on its hinge d.These metal rods can be switched on the metal band Z) by means ofswitch-levers g. On the opposite side of the bath-tub a metal rake 6,provided with as many teeth f as there are hingebars a, is also sohinged to the bath-tub that it can be turned up. To this rake the otherpole is fixed.

For the purpose of conducting the current into the bath fluid electrodesh, reaching almost to the bottom of the tub, and consequently nearlyequal in length to the depth of the tub, are movably arranged on themetal bars 0, as Well as on the metal teeth f of the rake 6. At theirupper ends these electrodes are provided with a metal socket i, in themidst of which an oblong opening Z is arranged, through which the bars 0fare passed. The metal socketsof the electrodes being provided withthese oblong openings Z, through which bars 0 f may be passed, Fig. 8,the electrodes can be displaced, as well as laterally turned and fixed,by screw upon the bars. In this way the metal sockets 2' of theelectrodes h are firmly pressed against the bars Serial No. 13,596. (Nomodel.)

0 f, thereby insuring agood contact. As the electrodes can be displacedand turned 011 the conducting-bars c f, the intensity of the current canbe changed in every place of the bath. Moreover, further variations inthis re the bath without it being necessary that the metal parts of theelectric equipment come into contact with the bath fluid, wherebydecomposition might take place.

The current is conducted to the tub by a switchboard fastened to it. Onsaid switchboard a rheostat, the handle of which can easily be turned bythe person in the bath, is provided for regulating and adjusting theintensity of the current. In like manner a voltmeter and ampere-meter,as Well as a current-reverser and electric alarm,are arranged on theswitchboard.

I claim- 1. In an electric bath, the combination of a bath-tub with aseries of rods arranged on opposite sides thereof, switch-levers forthrowing some of said rods in circuit,and electrodes supported upon saidrods and projecting into the tub, substantially as specified.

2. In an electric bath, the combination of a bath-tub with a series ofpivotally-movable rods arranged on opposite sides thereof, switch-leversfor throwing some of said rods in circuit, and electrodes adj ustablysupported by the rods and projecting into the tub, substantially asspecified.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
